Green
Um he is age gap MC is much younger, mind your triggers
Red bc of 10 yr age gap and always comparing mc to a child
10 years isn't a big deal, as long as you're 20+, which they are.
Red, because he is inconsiderate of MCs feelings and keeps on hurting him by bing wishy washy.
Yellow? Not great, not terrible, but not good for the MC.
Ml is good? Green, red or black?
